RAIL SUPPORT.

Application filed July 13,

This invention relates to certain new and useful improvements incomposite railroad stringers and ties and more particularly to crossties of the insulated type. y

The main object of the invention is to provide a simple, efiicient anddurable rail support which comprises few parts which are so interlockedwith each other as to impart great strength and rigidity to the entirestructure.

Another object of the invention is to provide a generally improved crosstie construction of the character described which is made up of a steelskeleton frame, the several parts of which are made of standardmaterials capable of being produced at any properly equipped steel mill,and so constructed that the tie may be put together, either at the millor at the track side and the concrete filling placed in position afterthe skeleton structure of the tie has been put in place.

Another object of the invention is to provide a cross tie constructionwhich will not become buckled or broken as a. result of heavy loadspassin overthe rails and which will not become center bound.

A still further and important object of the invention is to provide across tie construction wherein a maximum support is given to each railand lateral deflection of the rails is prevented and in which the tworails are allowed a limited up and down movement independent of eachother. 7

Further and more limited objects of the invention will appear as thedescription proceeds and by re erence to the accompanying drawing inwhich Fig. 1 is a top plan view of my improved tie with the railssecured thereto; Fig. 2 is a vertical sectional view on the line 2-2 ofFi 1; Fig. 3 is a vertical sectional view on t e line &3 of Fig. 1; Fig.4; is a vertical sectional view on the line 44 of Fig. 1; Fig. 5 is aperspective view of one of the blocks to which the rails are secured;Fig. 6 is a top plan view of the skeleton frame as sembled; and Fig. 7is a view in side elevation of the skeleton frame.

Referring now to the drawing in which like parts are referred to by thesame'reference characters, the numerals 1, 2, 3 and 4 designate plateswhich form a partof the skeleton frame and which are shaped as shownmost clearly in Figs. 4, 6 and 7. These plates are preferably made ofsteel and have portions 5 cut out therefrom and bent as shown most 1927.Serial No. 205,340.,

clearly in Figs. 4, 6' and 7 the purpose of which Wlll hereinafterappear. The plates 1, 2, 3 and 4 are secured together and held in spacedrelation with respect to each other by means of spaced, parallel,transversely extending cross beams 6-which extend through slots in theopposite ends of the plates 1, 2, 3 and 4. The cross beams arepreferably channel shaped in section and welded to the plates so as tohold the same against displacement. It will also be seen that the outerplates 1 and dare slightly inclined so that water will be drained offand away from the tie. This inclination of the outer plates also servesto strengthen that portion of the tie on which the rails rest.

By an inspection of Figs. 1 and 2, it will be seen that the plates areso spaced that the distance between the plates 2 and 3 is greater thanthe distance between the plates 1 and 2 or 3 and 4. The skeleton framewhen assembled appears as shown most clearly in Figs. 6 and 7. Theskeleton frame is placed in a form and concrete is poured in to fill thespaces between and adjacent the plates. The bent portions 5 interlockwith the concrete and serve to reinforce and strengthen the entirestructure. Before the concrete is poured wedge shaped blocks arepositioned between the plates 2 and 3 and spaced apart. These blocksserve to provide a pair of wedge shaped openings 7 and 8 on each side ofthe completed cross tie. lVhen the concrete has hardened and set. theform and the blocks are removed. ledge shaped blocks 9 and 10, one ofwhich is shown in detail in Fig. 5, are then positioned within theopening 7 and 8. These blocks 9 and 10 fit neatly within the openings 7and 8 as shown 1n Fig. 3 and rest loosely therein. The tie plates 11rest on the top of blocks 9 and 10 and the rails 13 and'lt are fastenedto the blocks by means of spikes 15 which extend throughthe tie platesand into the wooden blocks. It will thus be seen that the rails may havean up and down movement independent of each other and that there will beno lateral deflection of the rails. It will also be clear that due tothe shape of the openings and blocks the strain will be equallydistributed over a comparatively large area.

The skeleton frame may be shipped in a disassembled or knocked downcondition and may be assembled atthe track side. The bot-- tom edges ofthe completed tie are inclined 'my invention to scribed comprising aplurality upward slightly as shown in Figs. 2 and at. This inclinationof the outer edges of the tie permits the ballast 7) to be readilytamped around and under the tie.

It will be clear that I have provided a tie or rail support whichaccomplishes the objects of the invention as hereinbcfore stated.Various changes may be made in the details of my construction withoutdeparting from the spirit of my invention. For example, the blocks 9 and10 may be made of metal or reinforced concrete, instead of wood, and theflanges 1, 2, 3 and 4 as well as the cross beam 6 may be of differentshape. I therefore wish be limited only in accordance with the scope ofthe appended claims.
